To evaluate the correlation of dietary patterns with low muscle mass, strength and quality in Chinese adults. Based on the second resurvey of China Kadoorie Biobank, factor analysis was conducted to derive dietary patterns from 20 food groups. Low muscle mass, strength, and quality were defined as the sex-specific lowest quintile of appendicular skeletal muscle mass index (ASMI), total skeletal muscle mass index (TSMI), handgrip strength and arm muscle quality (AMQ) according to Asian Working Group for Sarcopenia recommendations. Logistic regression models were used to evaluate the correlation of dietary patterns with low muscle mass, strength, and quality. Two major dietary patterns were extracted. The balanced dietary pattern was characterized by the intake of a variety of foods, whereas the rice-meat dietary pattern was characterized by high intakes of rice, meat, poultry and fish. Individuals who had the highest quintile score of the balanced dietary pattern were less likely to have low TSMI, handgrip strength or AMQ(=0.83, 95%: 0.74-0.95 for low TSMI; =0.64, 95%: 0.56-0.74 for low handgrip strength; =0.82, 95%: 0.72-0.93 for low AMQ; for trend <0.05). And those who scored higher on the rice-meat dietary pattern had lower risk of low muscle mass and strength (=0.67, 95%: 0.55-0.82 for low ASMI; =0.69, 95%: 0.56-0.85 for low TSMI; =0.74, 95%: 0.60-0.91 for low handgrip strength; for trend <0.05). Individuals followed the balanced dietary pattern, as well as those who followed the rice-meat dietary pattern, had better levels of skeletal muscle mass, strength and quality.
评估中国成年人饮食模式与低肌肉量、力量和质量之间的相关性。基于中国嘉道理生物银行的第二次再调查，通过因子分析从20个食物组中得出饮食模式。根据亚洲肌少症工作组的建议，低肌肉量、力量和质量被定义为按性别划分的四肢骨骼肌质量指数（ASMI）、总骨骼肌质量指数（TSMI）、握力和手臂肌肉质量（AMQ）的最低五分位数。使用逻辑回归模型评估饮食模式与低肌肉量、力量和质量之间的相关性。提取出两种主要饮食模式。均衡饮食模式的特点是摄入多种食物，而米面肉饮食模式的特点是大米、肉类、家禽和鱼类的摄入量较高。均衡饮食模式五分位数得分最高的个体患低TSMI、握力或AMQ的可能性较小（低TSMI时，比值比=0.83，95%置信区间：0.74-0.95；低握力时，比值比=0.64，95%置信区间：0.56-0.74；低AMQ时，比值比=0.82，95%置信区间：0.72-0.93；趋势P<0.05）。而米面肉饮食模式得分较高的个体肌肉量和力量低的风险较低（低ASMI时，比值比=0.67，95%置信区间：0.55-0.82；低TSMI时，比值比=0.69，95%置信区间：0.56-0.85；低握力时，比值比=0.74，95%置信区间：0.60-0.91；趋势P<0.05）。遵循均衡饮食模式的个体以及遵循米面肉饮食模式的个体，其骨骼肌质量、力量和质量水平更好。
